hallmarks in Alzheimer’s disease (AD). Their aggregation forms are thought to be toxic to the neurons in the brain. A series of new 1,2,3,4-tetrahydro-1-acridone analogues were designed, synthesized, and evaluated as potential dual inhibitors for Aβ and tau aggregation. In vitro studies showed that compounds 25–30 (20 μM) with N-methylation of the quinolone ring effectively inhibited Aβ1-42 aggregation
淀粉样蛋白-β(Aβ)和tau蛋白是阿尔茨海默氏病(AD)的两个重要标志。它们的聚集形式被认为对大脑中的神经元有毒。设计,合成和评估了一系列新的1,2,3,4-四氢-1-ac啶
酮类似物,将其作为潜在的Aβ和tau聚集双重
抑制剂。体外研究表明,具有
喹诺酮环N-甲基化作用的化合物25 – 30(20μM)有效抑制Aβ1-42聚集84.7%–99.5%和tau聚集71.2%–101.8%。讨论了它们的构效关系。尤其是,有30种物质可以穿透血脑屏障,与Aβ1-42结合并与tau结合,抑制Aβ1-42β-折叠形成,并防止tau在活细胞中聚集。
